Read these Safety Instructions before using the switch for the first time and follow the Operating instructions.
Safety instructions
1.
The installation, initial operation and maintenance should only be carried out by a qualified expert with electrical know-how.
2.
Comply with the local and statutory rules and/or the VDE0100.
3.
Before electrical connection, check the specifications on the data plate and the technical data of this manual.
4.
A fuse must be connected in series to the supply voltage, according to the Standard and Normative documents.
5.
Protect the signal contacts of the limit switch against voltage peaks when inductive or capacitive loads are connected.
6.
The device may be put into operation only if the protection made of Porexpan and placed inside the housing has been removed. This is only a
protection during the transport of the device.
7.
The device may be put into operation only if the electrical connection is correct. To secure the type of protection, the sealing cap and the gasket
must be placed correctly and the screw nut of the cable gland has to be fixed and fastened to the cable entry.
8.
The earth connection of the device has to be installed in such a way that mechanical damage will be excluded.
9.
Protect the controller from vibration and shakes. The vibration can provoke premature damage to the controller and may become useless.
10. The blade must not be hit by the filling stream. To avoid this, deflect the filling stream or install a deflection screen or a protection roof. It is also
recommended to install a protection roof when the controllers are used as empty-indicator or medium-indicator in silos where vaults could be formed
or where high loads above it could exist.
11. Avoid the installation of standard devices in ambient with vapour or with several changes of temperature. There are specific models for these
applications with different sealings rings and bearings that can extend the lifetime of the device.
12. Ask for rotary levels with the special sealing ring made of Stainless Steel-PTFE-Viton in applicactions with aggressive products or with micronized
bulk solids.
13. The connections of the single components as like as blade, shaft, extension, anti-buckling protection, etc. are permissible only with the attached
pins.
14. Switch off the power supply, before disconnecting the device.
